Summary
Most runners ask one question before a race: did I finish my training plan? But fitness and race readiness are not the same thing — and in this episode, Zoë and TJ break down the physiological and psychological framework that actually tells you whether you're ready to toe the line. They start with the foundational model: fitness + freshness + specificity. Using the Banister fitness-fatigue model, they explain how both signals decay at different rates (fatigue's half-life is roughly 7–10 days; fitness is 40–45) — and why that gap is exactly where your race-day performance capacity lives. From there, they go sign by sign through five indicators you're ready — including aerobic decoupling and cardiac drift as readiness metrics, what glycogen supercompensation actually feels like during taper, why race-specific physiological systems (VO2max, lactate threshold, SGLT-1/GLUT-5 gut adaptation) can't be faked on race day, and how pre-race anxiety and pre-race arousal are the same physiological state with a different cognitive label. Then the five signs you're not: climbing out of a fatigue hole your neuroendocrine system is still broadcasting, missing race-specific work that willpower can't replace, running on a pain you've been rationalizing, under-fueling and under-sleeping your way to the start line, and the hardest conversation in coaching — when your goal and your fitness aren't in the same zip code. They also get into: Hot or Not on energy drinks at aid stations, AI-generated Spotify playlists vs. human curation, multi-day races and FKTs, and Prancercise (yes, really).
